A represents the framework of my machine, which framework is of suitablesize,

' shape and construction.

' The butter or other material to be packaged or wrapped and cut intosuitable cakes or squares is arranged on the slatted endless carrier 2.This-carrier operates in horizontal planes, and passes oversuitablesprockets 3- 3. This carrier is given intermittent motion bysuitable mechanism operated from the drive-shaft 4, Figs. 1', 2 and 3.As here shownythe step by'step movement-of the carrier 2 is e'fi'ectedby a ratchet 5 of sprocket 3,-and 1a pawl-'6 pivotally mounted on .alever 7, which levcltpis hung to swing on said sprocket.- A link 8connects the lever 7 with a lever arm 9 which is rigidly attached 'to arock shaft 10. The rock shaft 10 has an operating rigid arm '11, :towhich is connected a link 12 extending back to a yoke 13 carried by thelever 14, which is fulcrumed'to The yoke 13 .has a longitudinal guide 16engaging a crank 17 .on a shaft {18. Shaft drive-shaft 4 through themedium of the intermeshing gears 19-20. Shaft 4 is.operat-ed "from anysuitable source of power con -necting with the band pulley 21. Thus ateach revolution of shaft 4 the carrier 2 moves forward one step andcarries the square of butter, or other material to be wrapped, over theforward incline of the carrier and against .a spring-actuated, pivoted,yieldingly-mounted stop plate 22, Figs. :1, 11, '13 and underneath acurved top guide plate 22. This stop plate 22 is pivoted atitsvendszia'djacent to its lower edge, and performs the double functionof preventing 'the butter forward endof the carrier 2, and subsequentlyof bridging the gap between the carrier and a pocket 23 of the wheel 24,and thereby forming an inclined support over which the square of butteris pushed from the carrier into the pocket in a manner shortly to :bedescribed.

The carrier wheel 24 turns loose on a stationary horizontal shaft 25,and there is any 18 is d-riven constantly from suitable number ofpockets 23 arranged around the periphery of the wheel. As here shown,there are five of these pockets, because that is the number whichpractice has shown to give the best results. The wheel turns in avertical plane and it is given a step by step movement by any suitablemeans. As here shown, the step by step movement is effected from theyoke 13, Fig.

29, by means of a connecting rod 26 pivoted to the lever 27, Figs. 29and 32, which lever isfulcrumed to turn freely about the hub of wheel24. The outer end of the lever 27 carries a spring-actuated finger 28which has a shoulder portion 29 to engage a tooth 30 on the periphery ofthe disk 31, which latter is fixed to the hub of the wheel 24. At eachcomplete forward movement of the lever 27,

- a notch-34 close to a tooth at the end of each forward movement of thewheel, and

temporarily lock the wheel against any further movement. This springlatch 33, or detent, Fig. 27, is lifted on the next forward ,movement ofthe finger 28, by the-finger 33 riding under the latch and lifting-thelatter just prior to the engagement of the shoulder 29 with the tooth30. This serves to lift the latch over the tooth and allow the wheel torevolve.

The cube of butter or other article to bepackaged, and which is hereinrepresented by the character I), after it is deposited by the carrie -2against the spring stop plate 22, is grasiied at the ends by twoyieldinglysupported clamp members 36 carried on the spring arms'37,which latter are curved outwardl at their upper ends and attached'to asliding frame 38. This frame 38 consists of two bar slidably mounted insuitable guides 3939 on a fixed part of the frame A and arranged tooperate at an incline, and the grippers 36 are adapted to grasp thesquare'of butter endwise and move the same from off the carrier 2 andinto a pocket 23; the movements of the various parts of the machinebeing so timed that the wheel 24 will be stopped each time apocket23 isdirectly in the 'pathof the article which is gripped by the clampmembers 36 of the carrier 38. The construction of these clamp. members36 is shown'in Fig. 12, in which a convex plate 40 on a clamp 36receives a screw 41 passing through a perforation in the arm 37.A'spring 42 is inter osed between the head of the screw 41 an the arm 37and serves to hold the parts in position;

The periphery of they while the eonvexed plate4t) forms a rockingbearing-to" enable the clamp 36 to adjust itself squarely to the end ofa cube of butter. Lugs 42 limit the turning movement rockshaft 48carries the downwardly projecting arms 49 which connect by links 50, at51, with the slides 52, which latter carry the end folding devices110111-112, hereinafter to be described. I

The operation of the carrier 38 and clamp members 36 is as follows:Onthe oscillation of the rock shaft 48 in one direction the brackets 44first move downward slightly,

sliding on the side bars of the frame 38, the latter remainin stationaryagainst the operation of a suitable friction device, as thespring-pressed pins 55, Fig. 14. In these initial independent movementsof the brackets 44, the toggle arms 43 are operated to press inwardlythe clamps 36 and grasp any article which is disposed between them. Thisinward movement of the clamps 36 toward each other continues until thebrackets 44 slide down the side rails of the. frame 38 and encounter thelowermost stops 45, whereupon the whole frame 38, with the clamps 36 andthe object to be wrapped between them, is moved forward and downwardly,thereby turning the plate 22 froma'vertical position into a horizontalone, as indicated in Fig. 15, and the object I) to be wrapped is carriedoff the carrier 2 across the plate 22 and into the pocket 23.. Theclamps 36 each have a rearwardly extending heel-piece 36 which slidesover the plate 22 when pushed down into inclined position,

as shown in Fig. 8, and maintains the same depressed while the cube 7)is being put into i the pocket.

synchronously with the operation of the machine and the stoppage of oneof the pockets or boxes 23 at the receiving point immediately in advanceof the carrier 38, a

sheet of paper, cloth, or other wrapping material is moved across thepocket and between the latter and the advancing cube of butter, thesheet being seve rcd at the proper length, and when the butter movesinto the pocket it carries the severed wrapper along with it, leaving aportion of the wrapper projecting sufiicient y on all sides for foldingpurposes. The wrapper-forming material 18 preferably in the form of acontinuous strip,-1-epresented at 60, and wound upon a roll 61 carriedon an extension bracket 62 of the frame. The strip 60 passes through theframe 38 substantially at right angles to a line of reciprocation of theframe and proximate to the receiving pocket 23. The strip is adapted tobe grasped at the lower end by a pair of grippers 63, Figs. 1-5-6- 7;these grippers each comprising a pair of hinged jaws which are pivotedat 64 to a bracket 65 which is free to slide on the fixed guide 66. Eachjaw member 63 has'an outwardly extending arm 67, and these arms 67 ofeach pair of grippers connect with a yoke 68, which latter connects witha rod 69 extending upward and connecting with a grip plate 70. Thisplate 70, more clearly indicated in Figs. 33, 34 and 35, has its endssliding in the inclined slots 71 in the brackets 72, which are free tomove up and down on the stationary guide 66. These brackets 72 carry aplate 73, which latter cooperates with the sliding gripper plate tograsp the strip of wrapping material 60 which is passed between theplates 70 and 73. The actual gripping and pulling of the paper from theroll 61 is done by the grippermembers 70-73 which are always above thepocket and above the cutting knife 75, while the function of the lowergrippers 63 is merely to engage the edge of the paper and pull the sameacross the pocket and hold it taut without gripping it very tightly. Itis understood that pushing up on the plate 70 and temporarily holdingthe plate 73 stationary will cause the pintles at the ends of the plate70 to ride upward in the slots 71 and open the jaws formed by "these twoplates. A reverse movement of the plate 70 causes the jaws to close andgrip the wrapping strip completely across its len th. The reciprocationof the paperfee ing means, represented by the grippers (i3 and plates70-73, is effected by connecting the lower sliding brackets (35 by rods7 4 with the ends of the levers 9, Fig. 1, the lovers 9 serving tooperate both the'carrier 2 and the paper-feeding means.

At the moment that the paper-feeding mechanism reaches the lowest pointof its travel and has operated to draw the lower end' of the sheet ofpaper across the pocket, the cutting mechanisnn represented in Figs. 5-5is operated.- This cutting mechanism consists of a knife 75 preferablymade widest at the middle, as shown, and mounted to slide transverselyof thewrapping strip 60 on suitable guides 7 6 on a fixed part of theframe. The ends of the knife have projections 77 operating in slots 78ofcam 79. There is preferably one of these cams at each side of themachine, and these cams are mounted to oscillate on suitable pivots 80.The cam slots 78 are so disposed that when the cams 79 are rocked in onedirection the knife will be moved outward from the wrapping strip 60,and when rocked in the opposite direction the knife will be moved tosever the strip. At the same time that the knife is moved in against thewrapping material, a plate 81 is brought in toward the knife and againstthe opposite side of the strip (30 to support the after during thecutting operations, and to cooperate with the knife as a cutting member.This plate 81 is pivoted at 82 to the frame above the knife, and it haspintles 83 operating in the cam slots 84 in the cams 79. The arrangementof these cam slots 7 8-84 is such that the plate and knife willcooperate in the proper manner to open and close, according to thedirection in which the cams 79 are rocked; the plate 81 having alengthwiseextending slot knife, and an edge of the slot and the knifecoacting shears-fashion.

The oscillation of the cams is effected by the following means: Each camhas a crank arm projection 79 connected by a link 53 with a crank 54 atthe end of a shaft 54, Figs. 21, 21. Shaft 54 carries a pinion 54:adapted to mesh intermittently with a mutilated gear 120 on shaft 121.Shaft 121 in turn carries a pinion 122 intermittently meshing amutilated gear 123 on shaft 18. The manner of timing the operation ofthese several shafts 54'-121-18 will be more particularly referredtohereinafter. Suffice it to say at the present that the shaft 18 isrevolved continuously, and that shaft 121 makes one complete revolutionduring a half of a revolution of shaft 18 and remains quiet during theother half of the revolution of shaft 18, while the shaft 54 makes onehalf of a revolution during the revolution of shaft 121 and remainsquiet during the revolution of the other half of shaft 121; the severalgears 54 -120 and 122-123 being properly .85 at its lower edge toaccommodate the proportioned, so that shaft 54, which operates theknife, .will make one complete revolution in one-half the time thatshaft 121 does, and one-quarter of the time that shaft 18 does.

Just below the lowest point oftravel of the grippers 70-73, and justabove the knife, is a yieldingly-mounted' plate 86 which is adapted tobear lightly against'the paper drawn through the knife and hold thelower edge of the unsevered portion of the paper even and straight andin proper position, :so that-when the paper-gripping means are raisedupward again to draw down a fresh section of'wrapping material, thegrippers 63 will be sure to engage the lower end of the wrappingstrip. Y

The drawing down of a strip of wrapping material across a pocket, andthe cutting off of a section of the desired length, take place duringthe movement of the butter carrier 38 between the conveyer 2 and thepocket 23, and is so timed that the cube of butter moves a' sheet ofpaper into the pocket, thereby forming the initial fold of the paperabout three sides of the cube.

As soon as the material to be wrapped and the wrapper are placed in thereceiving pocket, the latter is closed to grip the material and hold itsecurely until the same has been finally wrapped and is ready fordischarge from the machine. As shown in Fig. 17, each pocket has oneside as 87, lunged at its inner angles, as at 88, and provided with 'acrank arm extension 89. Each crank arm 89 is connected by a rod 90 whichextends in through the periphery of the wheel and through the hub, withthe inner end of the rod 90 running over a cam sleeve 91. As shown inFig. 19, each rod 90 is preferably made in sections, with one sectiontelescoping inside of another, with a spring 92 disposed between thesections. A spring 93 is adapted to bear against the rim of the wheel 24and against a pin 94 on rod 90, andto exert a tendency always to openthe pockets. The object of making the.rods 90 in two telesco ingsections, as

' shown, is to provide a yie ding connection for the hinged side 87, sothat this side 87 and the pocket may adapt themselves to cubes varyingslightly in si z e and thereby prevent injury to the cubes. The camsleeve 91 fits within the hub of the wheel 24, and has a cut-awayportion 95 extending a portion of the way around its periphery, and intowhich cut-away portion the inner end of the rod 90 will periodicallydrop, thereby opening out the hinged side 87 and allowing the packageeither. to be received into the pocket, or delivered therefrom. The camsleeve 91' has a limited rocking motion on the stationary shaft 25, andwithin the hub of the wheel, and independently of the wheel, for thepurpose of opening and closing the pocket during the periods of rest ofthe wheel, for the purpose of receiving a fresh package and delivering acompleted one.- This independent rocking motion of the cam sleeve 91 iseffected by a rod 97 having a yoke 97 operated by a cam 124 of shaft 18.Cam 124 has a shoulder adapted, during a part of its revolution toengage a in 125 on the lower fork of the yoke 97 to shift the rod 97 1none direction; and during a succeeding part of the same revolution ofshaft 18, this shoulder on the cam will engage another pin 126 on theupper arm of the yoke and shift the rod 97,. and correspondingly rockthe cam sleeve'91 in the opposite direction. It is understood that themotion of the cam sleeve 91 need be very slight in .eitherdirection,-and takes place durlng only a fraction of a revolution ofshaft 18. Consequently, when rod 50 is ,moved to retract the slidecarrier 38 upward after depositing a square of butter into the pocket,the cam sleeve 91 terial, and close the pocket, and thereby grip thematerial and wrapper therein. As soon; as thisis done, and before thewheel starts to turn, a folding device, represented in Figs. 8 and 9, isoperated to make the first side fold in the wrapper. This side foldingmeans consists of'a roller 98 carried by the slides 99 which areoperatedby links 100 connectingwith-the arms 1010f a rock shaft 102. Thelatterhas a crank'arm 103 connected by a link 104 with a lever 105,which latter is operated by a cam 106 on shaft 18. The roller 98 isnormally below the mouth of the pocket-and moves approximatelytangential thereto, and between the wheel and the previously describedwrapper-feeding means; while another roller 107' placed on a fixed partof the framelis' arranged on the upper side of the pocket when thelatter is stationary, and substantially tangential thereto. The rollers98 and 107 are normally separated, so as to stand, respectively, belowand above the pocket when it is receiving a fresh charge. As soon as thematerial and the wrapper are put in the pocket, the'roller 98 is movedupward to fold over the flap c of the wrapper, Fig. 8, on to the butter.Then the wheel 24 is set in motion and the opposite flap d is carriedunder the stationary roller 107 and folded over, leaving only the endsof the wrapper to be closed. The rollers 98107 are each preferablymounted in their bearings so as to be easily removable, as shown in Fig.10.

The wheel 24, with the package thus inclosed on the sides, is turnedeventually to bring 'the package into operative position with the endfolding .devices 110-111112 by which the ends of the wrapper are closedand the wrapping operations completed. In the passage of the package andwrapper from initial receiving position infront of the carrier 38, tofinal folding POSltlOIl in front of the folders 110-111-112, the packagepasses beneath a curved guard plate 127 which operates to malntain theoverlapping side edges of the wrapper closed.

The end folders are shown in Flgs. 1- 22-2324, and comprise for each endof the wrapper a pair of centrally-disposed pivoted folding blades 110,sidewise folding blades-l11, and a folding member 112 0pera'tive atright angles to the planes of blades 111-110 These various foldlngdevices are mounted on the carriage 113 fixed to the slides 52, whichare connected, as before described, by the rods 50 and crank arms 49 and47 with the slide carrier 38. A single carriage 113 serves to carry thefolders for both ends of the wrapper, as

shown in Fig. 22. The blades 110 are pivoted loose on shafts 115journaled in the frame 113, and these blades have rearwardly extendingshanks 116 provided with angularly disposed slots 117. These slots 117accommodate the pins 118 of a cross-head 119. The cross-head 119 isconnected with the carriage so as to have both a movement in unisontherewith, and independent thereof, by means of the suitable bearings131 on the carriage 113. The reciprocation of the folding carriage 113to carry the folding devices into and out of operative engagement withthe package, is effected by suitable connections, as the rod 132connecting with the crank 133 on shaft 121. It is understood that bymeans of the guides 130, the cross-head 119 has a limited movementtoward and from the frame 113 for the purpose of opening and closing thefoldin devices 110-411, and for operating the fo ding members 112.

As shown in Figs. 22 to 26, inclusive, the side folders 111 are fixed tothe rock shafts 115, and these rock shafts carry the crank arms 134-135,which latter have angular ends with respective cam slots 136; theseangular ends being crossedand accommodating a pin 137 carried 'on thebar 138 projecting forward from and carried by the cross-head 119. Theslots 136 in-respective arms 134-135 are so disposed that one folder 111will operate slightly in advance of the other, so as to make a good evenfold. The folding members 112 are pivoted to the carriage 113 and havecrank arms connecting with the sliding rods 139, which extend backthrough suitable boxes in the cross-head 119. These rods 139 have.suitable stops 140 adapted to bear against the inner side of thecross-head 119, so that when the cross-head 119 is moved toward thecarriage 113 these stops 140 will be encountered, and will act to throwthe folding members 112 outward and away from each other, as shown infull lines, Fig. 22. The ends of the rods 139 on the opposite side ofthe cross-head 119 have the springs 141 to provide a suitable yieldingconnection, so that when the cross-head 119 is moved backward and awayfrom the carriage 113 the folders will be turned toward each other, asshown in dotted lines, Fig. 22.

From the foregoing, it will be understood that when the cross-head 119and car-- riage 113 are moved by the rod 132 in toward the wheel 24, thefolding devices 111 and 112 are first opened outward by an initialmovement of the cross-head 119 toward the carriage 113. The carriage 113is connected, as before described, by means of the slides 52, the rods50 and cranks 49 and 47 with the slide carriage 38; and the weight ofthese parts, in conjunction with the friction devices, Figs. 5 and 14,will prevent guide rods 130 sliding in,

too free a movement, such as might otherwise interfere with thisnecessary independent action of the cross-head 119 with the carriage113. The folding devices 111112 are opened and the folders 110 closedsubstantially as shown in Fig. 23, to accommodate the unfolded ends ofthe wrapper which project from each side of the adjacent pocket 23.

The various steps of folding the end of the Wrapper are represented inFigs. 23, 24. As the folders 110 move in across the end of the package,thefirst fold is made, as shown in Fig. 23. Then whenthe carriage andcross-head move back away from the wheel, there will be initialindependent movement of the cross-head antecedent to the movement of thecarriage, which will cause a slight separation of the folders 110, asshown in Fig. 24, for the purpose of giving an even crease to the sidefolds, which are next made by the closing in of the blades 111. Fig. 1",shows the end of the package immediately after the side folders 111 haveacted. As the cross-head and carriage are separated, and the carriagemoves away from the pocket, the folders 112 will be turned inward intodotted line position, as

shown in Fig. 22, to complete the final folding of the wrapper.

The next step in wheel 24 brings the the revolution of the foldedpackage into the osition represented at X, Fig. 1, ready to dischargedfrom the machine. At the same time it comes into this position X, thecamsleeve 91 is rocked so as to allow the pocket at X to. open anddeposit the wrapped package on to a pair of arms 140, which are fixed tothe rock shaft 10 and move up and down on each side of a suitableconveying belt 141 according as the shaft 10 is rocked. As shown in Fig.1, these receiving arms 140 are lifted, and are about to receive thecompleted package at X. On the next movement of the rock shaft 10 thesearms 140 will drop down on each side of the conveyer 141 and deposit thepackage on to the conveyor, whence it will be taken from the machine anddelivered wherever desired. Preferably the carrier 141 is given a stepby step movement synchronously with the various operations of the restof the machine by suitable means, as the connectin rod 142 leading tothe yoke 13 and connecting with an arm 144 on the shaft 145 whichcarries one of the rollers over which the conveyer 141 passes. The shaft145 has a ratchet 146 which is intermittently engaged by a springpressedawl 147 Y on the suitable actuation of the ever 144.

In Figs. 1-23, I have shown certain shafting and gearing, represented bythe characters 150-151-152-153, by which certain mechanism for cuttingthe butter into suitable cubes may be operated; said cutting mechanism.not being here shown, as y it forms an independent invention.

In operation, the material, such as butter, cut into suitable shapes ofpro er dimen-- sions, is fed one article ata time y the conveyer 2 overthe forward end ofthe latter against the normally; upright,"spring-actuated sto plate 22,'a'nd'beneath the curved top gui e 22.,The slidecarrier 38, being in retracted position," the arms 47 arerocked to cause the slide brackets 44 first to move down the side railsofthe carrier '38 and close in the rippers 36 against the end of thesquare o1 butter.. 'Atthe time that the arms 47 rock to move the slidecarrier 38 downward to carry the butter from the carrier 2 into thepocket 23, which is in position to receive the butter and package, theend folding carriage 113 is moved inward toward the wheel 24 to causethe folding devices 110 to make the initial fold, or the ends of awrapper which has been brought into position in front of the end foldingcarriage. Prior to the downward .movement of the slide 38 to carry thebutter'into the pocket, the paper gripping mechanism 63f70-73, shown inFig. 4, is operated to draw afresh strip of paper down acrossthe pocket,and the cutting mechanism, shown in Figsj5, 21, 21 is operated tosever astrip-of material, leaving the severed strip across the mouth of thepocket, and immediately in the path of the approaching square of butter;this strip and the square of butter being carried simultaneously intothe pocket. The cam 91 is then turned to close in the side 87 of thereceiving pocket, and simultaneously to open the pocket in position X,Fig. 1, and release a previously wrappedpackage. As soon as the butter,with the wrapper, has been deposited in the pocket by the carrier 38,the connecting rod 132 is reversed to pull back on' the end fO1d'.. ingcarriage 113.- This reverse movement of the carriage and cross-headI19operates, as before described, to actuate the folders 111112 and makethe folds-representedby b, w, in Fig. 1; and at-the same 'timethebackward movement of the carriage 113. operates through the slides 52,connecting rod 50, arms4947, and shaft 48, to retract the slide carrier38 upward into initial receiving posit-ion. Then the roller folder 98,in Fig. 8, movesupward to fold inthe edge 0 of the wrapper." Next thewheel is turned through the medium of the link 26 and the pawl andratchet mechanism, shown in Fig. 16, to brin an empty open pocket intoline with the side carrier 38, 'which is now retracting preparatory totaking a fresh cube of butter from the carrier 2. The turning of thecarrier carries the flap (Z, Fig. 8, of the wra per underneath thestationary roller 10; and closes down the end of the wrapper over thepreviously folded flap a.
